I'm running XP with a creative audigy EMU 0404 sound card. Just the other day after turning my computer on, I get no sound. I've checked all the connections, checked Device Manager, checked all the volume controls I could find, checked for muted boxes, and all of that. I've been running my card out line into a stereo receiver and then out to speakers from there. The receiver is still working as I've been able to listen to the tuner, and also I connected a dvd player audio to the receiver and heard the cd I put in the DVD player. So, it's something to do with the computer itself or the sound card. According to Device Manager the sound card is working fine. I also uninstalled then reinstalled the drivers for the sound card. Any help would be appreciated.
